Abstract (en)
An ejection recovering unit includes tube pumps which generate pressure for performing ink enforced discharge of ink jet heads by sequentially deforming flexible tubes (503) under pressure. Pressing rollers (505) are spring biased toward a direction of preliminary,pressurizing a spring for sequentially pressure deformation of tubes. This suppresses an increase in drive torque due to dispersion of accuracy of tubes (503), pressing rollers (505) and mounting parts thereof. A guide (506C) is provided to place the corresponding roller (505) in a state corresponding to a pressurizing state before the guide presses the corresponding tube (503). This prevents any change in torque due to sudden production of the pressurizing state. <IMAGE>
